VEGF Signaling Promotes Cell Growth and Metastasis in Extrahepatic Cholangiocarcinoma in a VEGF Receptor Mediated Pathway (ECC)

NCT02103179 | Unknown

• 1 other identifier: k0113011-2013ECC
• Study Type: observational
• Target: 20
• Locations: 1 country
• Sites: 1

Brief Summary

The investigators study the VEGF signaling in ECC cell lines,patients and its mechanism in ECC growth, proliferation and apoptosis.

Conditions

Extrahepatic Cholangiocarcinoma

Keywords

Extrahepatic cholangiocarcinoma; ECC; VEGF signaling

Outcome Measures

Primary Outcomes (1)

• the variation of the quantity of VEGF signal pathway genes in normal liver tissue,peri tumor,tumor and metastasis.

  the sections would be collected as previously described.Western blot,immunohistochemistry,PCR would be conducted to find out the variation between the normal liver tissue and tumor,tumor and meta(if have).

Study Arms (1)

ECC patients

Extrahepatic cholangiocarcinoma patients treated by surgical treatment

Procedure: surgical treatment

Interventions

surgical treatment PROCEDURE

all the patients in the study must have been treated by the surgery at the first time and have been confirmed as 'complete section' by the post-surgery radiological image.

Location

Biospecimen

Retention: SAMPLES WITHOUT DNA

Cut tissue into small pieces (\~2 mm2)and wash in drops of saline (1x PBS). Place pieces individually into LN2 in Styrofoam cup. Transfer pieces into LN2-cooled 1.5 mL cryovial. Pour out excess LN2 from vial, then seal and keep in LN2 until freezer storage.
